Add support for running fetcher in docker & publishing image (#422)

## Summary
Add support to run the fetcher service in docker. Also add rails to
publish to docker hub as a private image -
[ziplineai/chronon-fetcher](https://hub.docker.com/repository/docker/ziplineai/chronon-fetcher)

I wasn't able to sort out logback / log4j2 logging as there's a lot of
deps messing things up - Vert.x supports JUL configs and that is
seemingly working so starting with that for now.

Tested with:
```
docker run -v ~/.config/gcloud/application_default_credentials.json:/gcp/credentials.json \
 -p 9000:9000 \
 -e "GCP_PROJECT_ID=canary-443022" \
 -e "GOOGLE_CLOUD_PROJECT=canary-443022" \
 -e "GCP_BIGTABLE_INSTANCE_ID=zipline-canary-instance" \
 -e "STATSD_HOST=127.0.0.1" \
 -e GOOGLE_APPLICATION_CREDENTIALS=/gcp/credentials.json \
 ziplineai/chronon-fetcher
```

And then you can `curl http://localhost:9000/ping`

On Etsy side just need to swap out the project and bt instance id and
then can curl the actual join:
```
curl -X POST http://localhost:9000/v1/fetch/join/search.ranking.v1_web_zipline_cdc_and_beacon_external -H 'Content-Type: application/json' -d '[{"listing_id":"632126370","shop_id":"53908089","shipping_profile_id":"235561688531"}]'
{"results":[{"status":"Success","entityKeys":{"listing_id":"632126370","shop_id":"53908089","shipping_profile_id":"235561688531"},"features":{...
```

## Summary by CodeRabbit

- **New Features**
- Added an automation script that streamlines the container image build
and publication process with improved error handling.
- Introduced a new container configuration that installs essential
dependencies, sets environment variables, and incorporates a health
check for enhanced reliability.
- Implemented a robust logging setup that standardizes console and file
outputs with log rotation.
- Provided a startup script for the service that verifies required
settings and applies platform-specific options for seamless execution.
